Bathtub

ABSTRACT

A bathtub, including: a container, including a bottom outlet; and a plumbing trap, extending downwards from the bottom outlet and being juxtaposed thereto, thereby allowing cleaning the plumbing trap through the bottom outlet of the container.

TECHNICAL FIELD

The invention relates to the field of bathtubs.

BACKGROUND

FIG. 1 depicts a prior art bathtub, including the outlet piping thereof,prior to assembling it.

A prior art bathtub constitutes a container 12, being placed on thefloor 54, and includes a bottom outlet 50 having a relatively smalldiameter 52A, for connecting thereto a curved pipe 18, having as welldiameter 52A, in a sealed manner.

The term “plumbing trap” refers herein to a device forming a bendingpath, for capturing water to prevent entrance of sewer gas, whileallowing waste to pass through.

The other end of curved pipe 18 is connected to an inlet 56A of aplumbing trap 20A, having as well diameter 52A, being relatively small.

FIG. 2 depicts the prior art bathtub of FIG. 1, after assembling it, andat use.

Pipe 18 is sealably connectable to outlet 50 due to its small diameter52A.

Solid waste 58 sinks to the bottom of plumbing trap 20A, and furtherexits towards the sewage pipe 24. However, sewer gas of solid waste 58cannot enter pipe 18 and back to container 12, since solid waste 58 issunk in water 60, being partitioned by a partition 62.

The user may remove solid waste 58 from a top opening 64, since it has arelatively large diameter 52B.

This bathtub is disadvantaged in water leaks between bottom outlet 50and pipe 18.

GB2298661, EP0807721, US2003196262, U.S. Pat. No. 6,418,569 andUS2011308009 disclose trapping of the solid waste, but not preventingentrance of sewer gas.

There is a long felt need to provide a solution to the above-mentionedand other problems of the prior art.

SUMMARY

A bathtub, including:

-   -   a container, including a bottom outlet; and    -   a plumbing trap, being juxtaposed thereto.

DETAILED DESCRIPTION

The invention will be understood from the following detailed descriptionof embodiments of the invention, which are meant to be descriptive andnot limiting. For the sake of brevity, some well-known features are notdescribed in detail.

The reference numbers have been used to point out elements in theembodiments described and illustrated herein, in order to facilitate theunderstanding of the invention. They are meant to be merelyillustrative, and not limiting. Also, the foregoing embodiments of theinvention have been described and illustrated in conjunction withsystems and methods thereof, which are meant to be merely illustrative,and not limiting.

FIG. 3 depicts a bathtub according to one embodiment of the invention,prior to assembling it.

A bathtub 10 according to one embodiment of the invention, includes acontainer 12 having a bottom outlet 50 having a relatively largediameter 52B; and a plumbing trap 20B extending downwards from outlet50, and having an outlet 56B, having a relatively small diameter 52A.

Thus, the user may clean plumbing trap 20B from bottom outlet 50 ofcontainer 12.

In contrast to the prior art sealable connection of the pipe to thebottom of the prior art bathtub, here, preferably, container 12 andplumbing trap 20B are cast together, thus water cannot leak from one tothe other, in spite of the large diameter 52B therebetween.

The plumber only connects sewage pipe 24 to the outlet 56B of plumbingtrap 20B, from the side, as shown by arrow 70A.

FIG. 4 depicts the bathtub of FIG. 3 after assembling it.

Solid waste 58 sinks to the bottom of plumbing trap 20B, and furtherexits towards sewage pipe 24. Sewer gas of solid waste 58 cannot enterback to container 12, since it is sunk in water 60, being partitioned bypartition 62.

The user may insert a sieve 72A, as well having an inlet 74 having thelarge diameter 52B.

Then, the user may place a ring 76, for diminishing the effectiveopening to a diameter 52C. Ring 76 may include a sieve 72B.

Then, the user may place a cap or sieve 14, having the standard diameterof the prior art bathtub of FIG. 1.

FIG. 5 depicts the bathtub of FIG. 4 after placing the elementsdescribed in FIG. 4.

The user may connect sieve 14 to plumbing trap 20B by a screw 34, formaintaining the small diameter 52C of container 12.

Thus, in one aspect, the invention is directed to a bathtub (10),including:

-   -   a container (12), including a bottom outlet (50); and    -   a plumbing trap (20B), extending downwards from the bottom        outlet (50) and being juxtaposed thereto,        -   thereby allowing cleaning the plumbing trap (20B) through            the bottom outlet (50) of the container (12).

The bathtub (10) may be configured to connect (70A) the sewage pipe (24)directly thereto, being to the outlet (56B) of the plumbing trap (20B).

The diameter (52B) of the bottom outlet (50) is preferably larger thanthe diameter (52A) of the outlet (56B) of the plumbing trap (20B).

The container (12) and the plumbing trap (20B) may be cast together.

The bathtub (10) may further include:

-   -   a first sieve (72A), for being removably placed in the plumbing        trap (20B) below the partition (62) thereof,        -   thereby accompanying cleaning the plumbing trap (20).

The bathtub (10) may further include:

-   -   a ring (76), for being placed on the bottom outlet (50), for        diminishing the diameter thereof.
